Data for confirmed cases, active cases, recoveries and fatalities was exclusively sourced from COVID LIVE. Reliable data sources were extremely challenging prior to April and as such, minimal data is available from the early stages of the outbreak.
Similarly, data for the Victorian Aged Care outbreak was obtained from data based on press releases.

Breakdown of individual states. Victorian recovered numbers began to be accurately reported from 22nd March, with other states gradually providing this information. NSW/QLD recovered cases have only recently begun being reported and up until the most recent dates, recovered/active values were very approximate for these states. The extreme drop for NSW active cases in early June is a function of the changed reporting strategy implemented by NSW Health.

Fatality rate for Australian cases as calculated using two methods. Where no offset is included, the rate shown is simply the number of fatalities divided by the total number of reported cases on the same date. When cases increase during a new outbreak, this will skew the fatality rate lower. An alternative is to use an offset based on the fact the the median time from infection to symptom onset is 6 days, the median time from symptom onset to ICU admission is 11 days, and the median time from ICU admission to mortality is 7 days. When using the offset, the fatality rate is calculated as the number of recorded fatalities on a given date, divided by by the number of cases from 18 days ago. Whilst still flawed this may give a less biased estimate on the true fatality rate, and importantly, will always be higher than the alternative calculation. The intial fatality rate spiked above 30% during the intial outbreak under the offset approach, and as such, data is only shown after 20 Apr, 2020. All times used for estimation the offset were obtained from here

Growth factor for each State/Territory. Values are calculated using only locally-acquired cases. In order to try and minimise volatility a 14 day simple moving average was used, in contrast to the 5 day average as advocated here. This enables assessment of the growth factor over an entire quarantine period. This value becomes volatile when daily new cases approach zero as is commonly observed in small populations, and at the end stages of an outbreak. As a result, values are only shown when the 14-day average of new locally acquired cases exceeds 1.
The current 14 day growth factor is 1.06 which gives considerable cause for concern..
